Troubleshooting Cisco Unified Communications v1.0

This lab bundle supports the Troubleshooting Cisco Unified Communications Systems (TUC) course that teaches the skills needed to troubleshoot, monitor and maintain a Cisco Unified Communications solution. The learners use the Cisco troubleshooting methodology to diagnose, fix and test the provided trouble tickets. In particular, they employ various methods, such as the GUI, CLI, log and trace analysis, syslog output, SNMP, as well as dedicated monitoring and analysis tools, to find faults in the voice system components, such as Cisco Unified CallManager, Cisco Unified Unity, Unified Contact Center Express, Cisco Unified CallManager Express, Cisco IOS gateways and gatekeepers, and then resolve them. All exercises in the bundle use this topology:
